Question

Daca x-17x4=yx8=z:2:3=56:u=8,atunci (x+y)-(z+u)=?

Answer 1

x-68=yx8=z:3 : 2 = 56:u=8 
x-68=8
x=76 
y= 1
z:3=16
z=48
u=7
(76+1)-(48+7)= 77-55 = 22

Answer 2

X-17x4=8,vine X-68=8,vine X=8+68=76.__ ___________________________________Yx8=8,vine Y=8:8=1.______________ _________________________________ __Z:2:3=8,vine Z:2=8x3=24,vine Z=24x2=48.________________________ ___________________________________56:U=8,vine 56=8xU,vine U=56:8=7.__ _____________________________________(X+Y)-(Z+U)=(76+1)-(48+7)=77-55=22
